CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your F2X/F3X running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.Shipping Notes

Durable, Dogs love it
Color: Red
My Frenchie is a crazy chewer and can chew up a nylabone in a day, so I was looking for something that would last longer. So far this is holding up, and is pretty durable. Both my dogs like it a lot, it’s easy for them to grasp, and chewable but still very tough material. I suspect at some point it’ll wear down, but not for a while. The size was just as described / expected. Not too small and not too big

NOT FOR PLAYING CATCH.
Color: Blue
This toy is quite heavy, making it good for a chew toy or for fetch, but not for catch. It could very easily injure your dog as it damned near did mine.

Durable bone that you can add a spreadable treat to
Color: Blue
Our German Shepherd was 4 months old when we purchased this. She’s going to be 6 months soon. She has been teething really bad. We wanted some way to sooth her pain. This product was just what we needed. We put it in the freezer with some peanut butter in the center on both sides. Once frozen we give to our puppy. She loves it. When we open the freezer she recognizes the ziplock package that it was delivered in which we store it in our freezer. She jumps around until we give it to her. She loves it and it keeps her occupied for a while. It is very durable. I did not notice any smell when we received it. It does not make any noise. The plastic material is safe for animals. To clean I put in the dishwasher. The only reason I did not give it 5 stars is because sometimes the peanut butter gets stuck in it and may need to go through the dishwasher twice which is not a big deal. Or you can hand wash it. I found the dishwasher was best for us. You do not even have to put anything on it, but our pup likes it. I would recommend to others.
